Recipes for Health: Eggplant
People do have strong feelings about eggplant. If they don’t like it, they usually cite its bitterness or heaviness. Salting does improve eggplant’s texture if it’s to be fried, Parsons notes, but that’s the only reason to purge it.
The problem with frying is that eggplant will soak up every ounce of fat in the skillet, which is why so many eggplant dishes are heavy. But there’s an alternative. I get around frying eggplant, even in dishes where eggplant is sautéed, by roasting it first. Then I cut it into pieces and cook it again with the other ingredients in the dish. Roasted eggplant has a deep, complex flavor. As long as you don’t need firm slices, roasting is a great way to avoid making it heavy.
Eggplant is also terrific grilled, and you’ll be amazed by how silky and delicious it can be when steamed and tossed with a dressing.
Some people object to eggplant’s skin. That’s too bad, because the skin of purple eggplants contains its most valuable nutrient, a powerful antioxidant called nasunin, one of a type of flavonoid called anthocyanins present in many fruits and vegetables with red, blue and purple hues (berries, beets and red cabbage, to name a few). Choose the purple varieties when you shop, and leave the skin on.  Martha Rose Shulman
